rlhis invention relates to clamping devices for holding meat or other material 1n position to be slicedby the lrniije of a slicing machine.A

The object ot the invention is to provide a clamp which shall be ot improved construe tion and convenient and etlicient in operanionV in its l particularly pointed out 'in ythe appended claims.

In the drawings, i `Fig.V 1 is an elevation of a clamp einbodyingone form of the present invention.

Fig. 2 is a top plan view ot the clampshown iv The numerals 10`a1id11 designate upright posts, which may project upwardly trorn points adjacent the front` edge of themeat supporting table ot the slicing machine. The posts have smooth outer surtacesand are preferably cylindrical, although the cylindrical shape is not essential. Sleeves 1 2 and 13 are slidably-mounted on the posts 10 and y11 respectively and are provided with lool:-

ing levers 14 and 15 which `are pivotally mounted at k16 and 17 on .their respective sleeves. A clamping bar 18 is 'pivoted at' 19 to the locking` lever 1li and at 2O to a link 21, which is pivotally connected at 22 tothe locking lever 15. Thesleeve 12 is providedwith a handle 23 and the sleeve ,-18 is provided with a handle 2li, the handles being` rigid with their respective sleeves. lThe levers lala-nd 15 are each provided with an upper and lower f y verse movementV when placed into contact cam tace which projects through slots 25 and 26 in the respective sleeve 12 and 13 into position to engaoo the smooth surfaces of the uprights 10 and 11. Springs 27 and 28 normallyv hold the levers 11i and 15 with their lowerl bearing faces in contact with the uprights. This automatically `locks the sleeves from sliding` downwardly on their standards 10 and 11, so that the clami nig bar 18 is automatically supported in any position to which it is moved upon the uprights. lo'wnward pressure on theha-ndles, however, will kmove `the sleeves 12 and l13k downward for the reason that the pivots 16 and 17 are so close to the posts 1G and 117 respectively, that the pressure on the pivots will cause the lower contactsto slide upon the posts.

5. A clamp for holding material to he sliced comprising an upright standard', a sleeve slidahly mounted on said standar-ch a loelringlever having two holding portions arranged respectively' to hold said sleeve against movement in opposite directions on said standard, and a clamping element conneoted to said locking lever and arranged to n move said lever into position to resist movement of said clamp in either direction.

6. A clamp for holding material to he sliced com arising a standarcha slide mounted on said standard, a loclr for holding said slidetrom movement along said standard, a lock and arranged to automatically operate said lock to move said lock into operative engagement with said standard when force is exerted on said clamp to prevent movement of said slide under the influence of said itorce,

' and a handle connected with said loch and arranged to release said loc-lr to permit 1nove ment of said slide under the influence .of

torce exerted on said handle. p

7. A clamp for a slicing machine comprising a `standard having a sleevesliclahly mounted thereon, a llocking lever pivoted on said sleeveand having contact portions arranged to engage said standard reseeetively When said lever is moved in opposite direc-- tions upon its pivot, a. clamping element attached to said lever and arranged to antomatically operate said lever to lock said sleeve ,against movement'under the influence of torce exerted in either direction on said clamping element, and a handle connected with said sleeve to release automatically said locking lever when torce is exerted on said handle to move said sleeve along said standard. Y p' '8. A clamp for holding material to he sliced comprising a. pair et parallel guide rods, lsleeves mounted on said guide rods locking levers pivotally `mounted on said sleeves and having cam faces movable respectively into engagement with said guide rods upon movement ot' said levers in opposite directions, a` clamping har having one end connected With said levers and arranged to movesaid leversV to lool; said sleeves against movement under the influence et torce ei;ert ed on said clamping har in either direct-ion, and handles attached yto 'said sleeves ttor releasing said looking levers when moving said sleeves.

9. A clamp for holding material to he sliced comprising a pair ot spaced guide rods, sleeves mounted to slide on said guide rods respectively, locking levers pivotally mounted on said sleeves and having spaced contact portions on the ends thereof adjacent said guide rods, a clamping har pivotally connected With one or said levers at the end away from said guide rodsa a link connecting the opposite end ot' said clamping har with the end of the other ot' said levers away from its guide rod, and handles for moving said sleeves longitudinally along said guide rods.
